Re: Single Point of Failure?
My guess, FWIW, 0.5 cents worth, if that, is that the Internet will still carry on working, it's the substitution of names for IP addresses that will fail.
Reminds me of the incident, many years ago when one of my clients (in the UK) couldn't be accessed from some areas of the United States. Turned out that one of the sites in the DNS hierarchy, located in the States, had been compromised and was pointing searches to my client to the International Herald tribune's website instead. This was going on for weeks if not months. Used looking-glass servers dotted around the US to work out what was going on. Any DNS servers downstream of the infected one had to be re-pointed which, in those days, took a while to ripple through.
